Does the problem still exists in the latest kernel? Say 2.6.21-rc5. It will be helpful if you can attach your acpidump file.

I've tested on kernels 2.6.18 ~ 2.6.20, and each of them has the same error. I debug the drivers/acpi/scan.c and find the error message is dumped by the following code. and type == ACPI_BUS_TYPE_PROCESSOR, status == AE_ALREADY_EXISTS. There are 2 error lines in dmesg because, I think, I use a dual core CPU. Any suggestion is very thankful! static int acpi_device_set_context(struct acpi_device *device, int type) { acpi_status status = AE_OK; int result = 0; /* * Context * ------- * Attach this 'struct acpi_device' to the ACPI object. This makes * resolutions from handle->device very efficient. Note that we need * to be careful with fixed-feature devices as they all attach to the * root object. */ if (type != ACPI_BUS_TYPE_POWER_BUTTON && type != ACPI_BUS_TYPE_SLEEP_BUTTON) { status = acpi_attach_data(device->handle, acpi_bus_data_handler, device); if (ACPI_FAILURE(status)) { printk("Error attaching device data\n"); result = -ENODEV; } } return result; } - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
